Position

Smithsonian Tropical Research Institute (STRI) Staff Scientist, Director of Bocas Research Station, Balboa, Ancon, Republic of Panama.

Thèmes de recherche

Life history evolution in marine invertebrates, systematics, evolution of molluscs, conservation, functional morphology, paleobiology.

Her current research focuses on the evolutionary causes and consequences of mode of development in marine gastropods. Mode of development (planktonic vs. benthic, feeding vs. non-feeding, encapsulated vs. free-living) has important consequences for dispersal, gene flow, speciation rates and extinction rates. However it is unclear what factors maintain the stunning diversity in mode of development that we observed in many groups of marine invertebrates. Her research focuses on documenting the geographic and phylogenetic patterns in mode of development and combining these patterns with the results of laboratory experiments to test hypotheses about the factors driving its evolution.
